XRAY - Model racing cars

Hello everybody. I have a question for stick radio drivers.

For get a fast setup in carpet, the car is difficult to drive. Sometimes I need set the EXP Steering to -75% in radio. Anyone know any radio setup for more easily driving?

The corners that have very little degrees, it is very difficult for me turn very little the stick steering. Especially in carpet.

Any suggestions?

I think you need to remove some steering with the setup of the car, not the radio
